Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Intelbras IWR 3000N 1.8.7 devices allow disclosure of the administrator login name and password because v1/system/user is mishandled, a related issue to CVE-2019-17600.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

The Intelbras IWR 3000N router firmware 1.8.7 contains an information disclosure vulnerability in the v1/system/user API endpoint that exposes administrator usernames and passwords. An unauthenticated attacker with network access to the device management interface can retrieve cleartext credentials.

MitigationRestrict network access to the device's administrative interface, change any compromised credentials immediately, and apply vendor firmware updates when available.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify the device model
    Check if the device is an Intelbras IWR 3000N router by accessing the device's web interface or checking the device label
    Affected if The device is an Intelbras IWR 3000N router
  2. Check the firmware version
    Access the router administration page and navigate to the firmware version information page, or use the command 'cat /proc/version' or 'cat /etc/os-release' if you have shell access
    Affected if The firmware version is exactly 1.8.7
  3. Verify network accessibility of management interface
    Check if the router's web management interface (typically on port 80 or 443) is accessible from an untrusted network by attempting to reach http://<device-ip>/ from an external location
    Affected if The management interface is exposed to untrusted networks without firewall restrictions
  4. Test the vulnerable API endpoint
    Send an HTTP GET request to http://<device-ip>/v1/system/user (or the equivalent endpoint on the device) without any authentication headers
    Affected if The endpoint returns user account data including usernames and passwords in cleartext without requiring authentication

A user is affected if they have an Intelbras IWR 3000N router running firmware version 1.8.7 with the management interface accessible to untrusted networks, and the /v1/system/user endpoint returns cleartext credentials without authentication.
